The more important implication is of course that children of this harem are potentially old enough to be characters in Eternum...
That would not be in violation of Cari's earlier statement imo. Not a direct cameo of any kind. I don't know either Dorfnutter's brain is contagious or there might be something more to Eva even without the Syndicate stuff. We are seeing quite a bunch of her, more than Maat that's for sure.
Wait so Cari doesn't want a direct cameo from OIALT in Eternum???
Bummer...
if only we could meet a character inside Eternum we've never seen, only for it to say something along the lines of:
"Have you ever heard of the Sons of Astaroth?"
then Orion goes: "Weren't they some kind of cult that was supposedly around some years ago?"
and the character goes: "Yes they were actually real and did try to take over the world but my father managed to defeat them, then he had to disappear for some time. Took his 7 women with him and all"
Orion: "Wow that's pretty damn amaz... wait a second, did you say he has 7 women?"
Character: "Yep, 7 women, i kinda have 7 mothers and so many siblings i can't even count!"
Orion: "YOU HAVE 7 MOTHERS???"
Theen before he can go in more detail, Calypso randomly teleports Orion away to unknown places.
Now thats just my idea for a cameo.
And in Dorfnutter's wise words: (Look, I know it's a pipe dream...but a man can dream, alright?! DX)
